hi Cheryl
If you download my POI file set here
[You must be registered and logged in to see this link.]Save it where you can find it!
Then open
[You must be registered and logged in to see this link.] and load that file of mine, you will see that by clicking on any POI on the right the map will go to it and you can zoom in.
You can add new points to the file and even merge other file sets.
My file is for tomtom but when you come to save it from POI.com you can re save in a different format for other devices.
TRY it it really is easy
